- Automated Headspace Vial Sampler

Static headspace is one of the most popular techniques due to its versatility for analyzing volatile organic compounds (VOCs) in a complex variety of matrices. This is due to the elimination of tedious sample preparation steps and prevents contamination problems that are common to other sample introduction techniques. Teledyne Tekmar draws on our experience as a leader in low-level VOC analysis with the introduction of this companion autosampler to the Headspace product line.

Versa is the perfect solution for applications which require all the advantages of headspace analysis and is economical to fit any budget.

Versa comes with easy-to-use and proven TekLink 2G software that operates from Windows XP or higher and includes 21 CFR compliance tools. All instrument parameters, method scheduling and editing can be programmed.

Benchmark - Versa TekLink 2G is capable of performing useful diagnostics such as a Leak Check and Benchmark test. The Benchmark screen contains an interactive program that tests the Versa components including heaters, LEDs, valves, and the continuity of inputs and outputs.

Method Optimization Mode (M.O.M.) - Developing a new method to achieve the best analytical results for an application can be both difficult and time consuming. With Method Optimization Mode, the analyst can optimize different method variables such as platen temperature, sample equilibration time, pressurization, mixing, loop fill, and inject times and substantially shorten the time required for method development.

The method starts with a value and the parameter of choice will increment during the optimization process. For example, a value of 10 will increment the platen/sample temperature by 10oC for every sample. The first sample will be heated to 50oC, the next sample at 60oC, and so on.
